The resilience of GPS clock synchronisation to substation generated and external interference.
Determine the resilience of GPS clock synchronisation to substation generated and external interference that shall include:

  • An investigation and evaluation into the cause of poor reliability of the time synchronisation of certain GPS clock installation

  • Recommendation on actions that can be taken to improve reliability particularly if poor installation techniques or location of antenna have caused unreliability

  • Investigation into the ongoing suitability of current GPS based clocks to determine if these offer sufficient resilience to radiated interference or whether other time synchronisation systems or methods should be investigated either as an alternative or supplement

  • An investigation of alternative causes of GPS Clock time synchronisation unreliability to determine what these are likely to be and whether these are affected by environment or installation

  • Produce a strategy, specification and technical guidance on deployment of GPS clocks for protection systems where required.
